Sci-fi nerds, light-saber-toting geeks and everyday fans have spoken: The new “Star Wars” movie is out of this world.

“I’ve been a major ‘Star Wars’ fan for 30 years and this one was excellent,” said Carl Miller, 44, of The Bronx – one of 400 lucky New York Post readers who got to see “Star Wars: Episode III – Revenge of the Sith” at a special screening last night at the Loews Cineplex 84th Street on the Upper West Side.

The movie is the final chapter of director George Lucas’ 28-year “Star Wars” cycle – although it’s technically the third of the six movies. “Sith” finally explains the roots of Anakin Skywalker and how he evolved into the villainous Darth Vader.

“That was my favorite part – the force of the Dark Side,” Miller said. “Lucas did his thing.”

Fans praised the extended fight sequences – especially the light-saber duel between syntactically challenged Jedi leader Yoda and evil Emperor Palpatine and a climactic battle between Obi-Wan Kenobi and his one-time Jedi protégé Skywalker, who turns to the Dark Side.

When Skywalker is rebuilt – and crowned with Darth Vader’s famous black helmet and armor – the screening audience erupted into cheers.

Stephanie White, 29, a fifth-grade teacher from Park Slope, also found herself feeling the force of the Dark Side.

“The ending was very cool,” she said. “It was so melodramatic when Darth Vader rises up.”

And the end of the movie perfectly leads into the beginning of the fourth installment of the saga, the original “Star Wars,” released in 1977, showing baby Luke Skywalker on the desert planet of Tatouine as his aunt and uncle watch the famous double sunset.

“The best part was finally learning how Luke Skywalker and Princess Leia were separated and seeing him on Tatouine,” said Christian Romero, 20, of Queens.

Most of the crowd was just happy to get a chance to see the movie before anyone else.

“I was giddy like a schoolgirl all day,” said Michael Epstein, 34, an accountant from Manhattan.

Even the youngsters loved the dark film.

“It was great,” said Mark Rodriguez, 9, of Flushing, who showed up at the screening toting an action figure of General Grievous. “The fight between Obi-Wan and Grievous was awesome.”

Cindy Collazo, 21, of the Bronx dressed up as Princess Leia.

“I know I’m too old for this, but I just love dressing up,” she said, admitting that she’s only seen the first two “Star Wars” films.

“Now, I can’t wait until the next movie,” she said, only to be crushed when she was told that the saga was over.

“If I was a kid, my favorite thing would be Yoda climbing up on Chewbacca. Yes, I am a ‘Star Wars’ geek.”

The finale of the six-film saga opened in 18 theaters throughout the five boroughs and another 3,643 theaters across the United States. Many of them kicked off round-the-clock screenings with a 12:01 a.m. show this morning.

“Sith” is expected to gross well over $100 million this weekend and could shatter box-office records.

It’s also expected to spark massive absenteeism at workplaces around the world – with a potential loss of $627 million in productivity in the United States alone.

STAR WARS

“Revenge of the Sith” delivers something for just about every “Star Wars” addict – blazing scenes so sweet, even the Ewoks must have gagged. Here are The Post’s votes for the film’s most memorable – and missable – moments

MOST AMAZING EFFECTS

The opening 22-minute dogfight sequence – featuring Obi-Wan Kenobi and Anakin Skywalker piloting their ships in pursuit of Count Dooku’s rebels – is crammed with more racing, zooming and laser-blasting visuals than you can shake your Naboo at.

SAPPIEST DIALOGUE

When Princess Padme and Anakin get together, even Hallmark writers cringe. “You’re so beautiful,” says Anakin. “That’s only because I’m so in love,” says Padme. “No, it’s because I’m so in love with you,” says Anakin. Cut!

CUTEST WARRIORS

Chewbacca and fellow wookies get center stage when they battle the evil droid army on their home turf of Kashyyyk. Reached for comment, Chewbacca remarked, “Mrrwaaaaah!”

COOLEST MOMENT

As we’ve known since the original “Star Wars” came out, Darth Vader gets horribly disfigured. Watching him getting fixed up and fitted for the costume that makes him look like Dracula’s linebacker could almost turn you into a cheerleader for the Dark Side.

MOST UNEXPECTED ACTION HERO

R2-D2, who uses his attachments to slay droids like a metallic Kung fu master.
